Question

Rationalize the denominator. The variable represents a positive real number.

 

(cube root of 24t^3)/ (cube root 108t^2)

Answer 1

Hi Sha,

 

Think about what you would have to multiply the denominator by to get everything under the radical to a perfect cube.  For instance, if you have the cuberoot of x, you would have to mutiply by cuberoot x².  If you have cuberoot 4, you would multiply by cuberoot 2.

 

Is that enough of a hint to get you started?

Please let me know,
